Abstract

本发明是一种塑料输液容器用组合盖，主要由组合盖主体、机械式单向阀、橡胶垫片三部分组合而成，其特点是组合盖中采用了单向阀这种先进的原理，而且有效避免了传统组合盖中穿刺橡胶垫片产生落屑的问题；在使用时只需将易折扳手掰断，将塑料输液器的塑料针头穿刺单向阀内即可，单向阀上的输液孔会暴露在液体中打开通道完成输液，在停止使用时单向阀会随针头的拔出而进入固定套内，封闭输液孔，所以不存在漏液问题。

Description

一种塑料输液容器用组合盖
技术领域
本发明一种塑料输液容器用组合盖属于医药包装材料领域，具体涉及一种塑料输液容器用组合盖。
背景技术
目前市场上普遍使用的同类瓶盖为拉环式或掰开易折式,使用时一个组合盖一个大橡胶垫片，加药和输液在同一个橡胶垫片上完成，临床使用时容易出现漏液、橡胶垫片穿刺落屑，且橡胶垫片较大，消耗原材料较多，造成生产成本偏高。
发明内容
本发明的目的是要解决和克服上述现有技术的缺陷，提供一种新型的易折式塑料输液容器用组合盖，该瓶盖采用新颖的内部结构，先进的原理，使其外形美观、构思新颖、工艺简单、开启方便，是一种密闭性强、生产成本低、实用性更强的新颖的塑料输液容器用组合盖。
本发明采用下述技术方案：该塑料输液容器用组合盖主要由组合盖主体(1-3)、机械式单向阀(1-4)、橡胶垫片(1-2)三部分组成，其特征在于：所述组合盖对机械式单向阀(1-4)的应用,并且组合盖主体(1-3)内有两个完全分开的固定套,可将机械式单向阀(1-4)和橡胶垫片(1-2)分别紧密的固定在各自固定套内；所述开启扳手(1-1)与组合盖主体(1-3)的固定套部分紧密配合,开启方便。加药过程通过橡胶垫片(1-2)起密封和抱针作用；而输液过程通过机械式单向阀(1-4)起密封和抱针作用。组合盖利用了单向阀原理，使加药过程和输液过程在同一组合盖中通过不同方式完成，并且完全分开。
与现有技术相比，本发明有益效果在于：使用新颖的输液原理，加药和输液完全分开，避免了交叉污染，也降低了漏液的风险；通过对该组合盖结构的改变，橡胶垫片尺寸的减小，并且橡胶垫片只用于加药，从而使穿刺落屑大大的减少，并且降低了成本。这种结构也增强了其密闭性能和输液器的保持力，使其实用性增强。
附图说明
附图为本发明的结构示意图。
1-1为组合盖开启扳手、1-2为橡胶垫片、1-3为组合盖主体、1-4为机械式单向阀、1-5为机械式单向阀的阀门。
具体实施方式
本发明为一种结构新颖、原理先进的塑料输液容器用组合盖由组合盖主体(1-3)、机械式单向阀(1-4)、橡胶垫片(1-2)三部分组成，橡胶垫片(1-2)、机械式单向阀(1-4)和组合盖主体(1-3)采用凸凹卡装方式组合。橡胶垫片(1-2)、机械式单向阀(1-4)分别置于各自的固定套中，使其紧密配合。在加药过程中，橡胶垫片(1-2)为注射器钢针穿刺。在输液时，机械式单向阀(1-4)为输液器塑料针头进行穿刺，穿刺后机械式单向阀(1-4)的输液孔阀门(1-5)会离开固定套暴露出来，连通输液管进行输液；在暂停或停止输液时，拔出输液器塑料针头同时将机械式单向阀(1-4)带入固定套内，使输液孔阀门(1-5)被固定套封闭，起到密封作用。固定套上部有易折扳手，易于开启。
使用时，先将橡胶垫片(1-2)的易折扳手(1-1)开启，进行加药；等输液时再将机械式单向阀(1-4)的易折扳手开启，进行输液即可。
